High-resolution Mo Kα X-ray monochromatic backlight imaging using a toroidal crystal

Abstract

Curved crystal imaging is an important means of plasma diagnosis. Due to the short wavelengths of high-energy X rays and the fixed lattice constant of the spherical crystal, it is difficult to apply the spherical crystal in high-energy X-ray imaging. In this study, we have developed a high-energy, high-resolution X-ray imager based on a toroidal crystal that can effectively correct astigmatism. We prepared a Ge h5 1 1i toroidal crystal for backlighting Mo Kα1 characteristic lines (∼17.48 keV) and verified its high-resolution imaging ability in high-energy X-ray region, achieving a spatial resolution of 5-10 μm in a field of view larger than 1.0 mm.

A Wide-Range High-Resolution X-ray Crystal Spectrometer for Laser–Plasma Diagnostics

“…An implosion target may contain multiple tracer elements separately or simultaneously, and the characteristic lines of these elements frequently range in energy from a few keV to tens of keV [8]. Consequently, a wide-range and high-resolution crystal spectrometer is useful for such X-ray spectroscopic diagnostics [9,10].…”
